STREET-FLUSHING MACHINE.

Specification of Letters Patent.

Patented Mar. 6, 1917.

Application fi led June 10, 1914. Serial N 0. 844,123.

To all whom it may concern:

Be it known that I, WILLIAM C. INGRAM, a citizen of the United States, residing at Grand Rapids, State of Michigan, have invented new and useful Improvements in Street-Flushing Machines, of which the following is a specification.

My present invention relates to street flushing machines, and its object is to provide a machine of that character, which shall be simple and economical in construction and effective in operation, and which shall contain various new, improved and useful features hereinafter appearing.

This object is obtained by, and the invention finds a preferable embodiment in, the machine hereinafter described and illustrated in the accompanying drawings, in

which Figure 1 is a fragmentary right-hand side view of my street-fiushing machine:

Fig. 2 is a top plan View of the rear parts thereof, the tank being removed:

Fig. 3 is a front view of the horizontal flushing pipe and the flexible tube:

Fig. 4 is a right hand side view of the right hand supporting brackets therefor, etc., and

Fig. 5 is a fragmentary front view of the horizontal flushing pipe, enlarged.

In the construction illustrated, my invention has a suitable frame 1 traveling on the Wheels 2 and carrying a water tank 3.

A flexible tube or hose at conducts the water from the tank into a horizontal pipe 5 which is inclined to the direction of the machines travel, as particularly shown in Fig. 2.

A pair of brackets 6, one on each side of the frame support the pipe near its ends. Springs 7 may be attached to the pipe and swiveled on the screws 8 (to adjust their tension) carried by the brackets, whereby the pipe is pressed into its supported position on the brackets, and thus held against vibration.

A plurality of flushing vents are provided extending through the forward portion of the pipes wall, which in the construction shown carries projecting vent spouts 9.

Copies of this patent may be obtained for five cents each, by addressing the in the county of Kent and a tank, a horizontal These vents are flattened, as particularly shown in Fig. 5, their greatest cross-section dimension being in 'a line extending from the forward side 10 of each vent rearwardly and downwardly, by which formation, the forwardedge of each jet of water reaches the street at approximately the same time as the rearward edge.

The use of the plurality of vents with their several jets of water, instead of a continuous vent extending longitudinally of the pipe and emitting a single sheet of water, is nearly or quite as effective and much more economical of the water supply.

The inclination of the pipe to the direction of the machines travel along the street, combined with such travel, results in directing the jets at approximately right angles to the line of travel, or in other words, directly toward the street curb.

And the flexible tube 4 permits some movement of the pipe in any direction and allows it to readily adjust itself to its supported position on the brackets at its ends.

Without confining myself to details of construction shown or described, I claim:

1. In a traveling street-flushing machine, pipe having flushing vents, a tube leading from the tank to the pipe, brackets adapted to support the pipe near its ends relatively to the tank, and

springs adapted to press the pipe into its supported position on the brackets.

2. In a traveling street-flushing machine, a tank, a horizontal pipe having flushing vents, a tube leading from the tank to the pipe, brackets adapted to support the pipe near its ends relatively to the tank, and springs adapted to'press the pipe into its supported position on the brackets, and screws adapted to adjust the tension of the springs.

In testimony whereof I have hereunto set my'hand in presence of the subscribing witnesses.

WILLIAM G. INGRAM.
